Within high-performance air filtration, the HEPA H14 classification represents the gold standard for absolute purification. According to the European Normative EN 1822-1:2019 and the international standard ISO 29463, an H14 grade filter must deliver an absolute efficiency of ≥ 99.995% at the Most Penetrating Particle Size (MPPS), which typically ranges between 0.1 to 0.25 microns. Unlike H13 HEPA filters (99.97% overall efficiency), H14 filters reduce local penetration rates by a factor of 10, effectively eliminating ultra-fine dust, viral vectors, airborne bacteria, and toxic nanoparticles.
For engineering departments, procurement managers, and OEM/ODM buyers, selecting an HEPA H14 partner involves evaluating air resistance, initial pressure drop (Pa), and dust-holding capacity (DHC). Our custom formulations leverage optimized mini-pleat technology to minimize air-resistance curves, extending the operational lifecycle of HVAC systems while maintaining stringent ISO Class 4 cleanroom operations. This engineering balance protects critical manufacturing ecosystems and decreases long-term power consumption.

Shenzhen Snow Peak Clean Technology Co., Ltd. is an integrated high-tech enterprise, specialized in air filtration products research and development, production, sales, import and export trade. We produce and supply: Pre-filter, pocket filter, HEPA filter, chemical filter; replacement HEPA filter, car cabin air filter, humidifier filter; pocket filter media, melt-blown composite filter media, and other high-performance filter materials; provide high quality air purification solutions and products for indoor air pollution control and air conditioning systems of civil and industrial buildings, microelectronics, pharmaceutical, laboratory, school, hospital clean room etc.
Combined with our self-developed patented technology, our sterilizing antiviral HEPA filter can effectively filtrate fine particles, so that PM2.5 concentration down to 10 micrograms/m3, 5 times better than national standards; effectively inhibit the breeding of microorganisms, sterilization rate up to 99.9%, and no secondary pollution, removal of H1N1 virus efficiency as high as 99.99%.
Having 15 years of international air purification technology experience as the background, our company has standardized production workshops, dust-free filter workshops, and first-class technology HEPA filters production and inspection lines. Our facility is equipped with an independent research and development fully automatic air filter production line, featuring advanced machinery such as the AMADA CNC punch and CNC bending machine along with many other high-end equipment. This provides a strong guarantee for production capacity, precision, and strict quality control of our final air filtration and purification solutions.
End-to-end automated manufacturing processes ensuring consistency, reliability, and precision seal integration.
Tailoring modular flow systems to match regional requirements and environment-specific standards.
Within advanced wafer fabs and TFT-LCD cleanrooms, particulate contamination as small as 0.1μm can cause circuit open-loop faults. Our custom Gel-Seal H14 mini-pleat filters create laminar flow configurations to achieve ISO Class 3/4 environments, eliminating trace particulates and outgassing VOCs via sandwich-type media integrations.
In negative-pressure isolation wards, oncology departments, and pharmaceutical compounding laboratories, bio-aerosol management is critical. Shenzhen Snow Peak’s patented antiviral H14 solutions sanitize airborne pathogens on contact, capturing 99.99% of H1N1 viruses and stopping bacterial growth without downstream bypass leakage.
Commercial office towers, educational campuses, and airport terminals are increasingly upgrading existing air handlers to comply with modern clean air standards. Our high-flow panel filters and custom-framed configurations integrate with existing mechanical system housings, optimizing energy consumption with low initial pressure drops.
The global demand for high-efficiency air purification is governed by diverse local compliance frameworks. In the European Union, the EN 1822 framework establishes classification categories (E10-E12 EPA, H13-H14 HEPA, U15-U17 ULPA). In the United States, ASHRAE 52.2 MERV ratings specify standard industrial filtration capacities, while high-efficiency demands defer directly to IEST-RP-CC001.6 guidelines.
For multi-national operations, maintaining consistent compliance requires utilizing supply partners who understand regional certification protocols. Shenzhen Snow Peak clean technology solutions hold comprehensive CE and RoHS certifications. We conduct extensive testing protocols, including DOP (Dioctyl Phthalate) scan tests and DEHS particle counters, ensuring each H14 HEPA filter block meets or exceeds certified leakage threshold limits.
Furthermore, post-pandemic changes in ventilation guidelines (such as ASHRAE Standard 241 for Control of Infectious Aerosols) mandate higher clean air delivery rates (CADR) across shared public spaces, driving the adoption of H14 filters in retrofitted ventilation systems.
Applying H14 filtration in typical HVAC systems demands addressing structural load limits. The higher pleat density and tight pore structure of glass microfibers cause a higher resistance compared to standard MERV filters. We address this issue in our R&D department using progressive density layering. This technique balances the pre-filtration stages (using G4 and M5 media) with our main HEPA modules, keeping the initial system resistance within manageable limits (between 110–140 Pa at normal face velocities).
Leveraging localized materials and automated technology to deliver consistent quality and lower lead times.
Sourcing air filtration media from our Shenzhen manufacturing hub provides significant cost, raw material, and logistical advantages. Our integrated industrial supply network covers everything from raw melt-blown polymers to precision metal frame fabrication. This vertical integration allows us to respond quickly to custom order specifications while avoiding long material transit delays.
Additionally, our automated production lines minimize manufacturing variability. From computerized pleat forming to mechanical hot-melt glue distribution, automated processes protect the sensitive media structure. Our facility is equipped with AMADA CNC punch and bending machines, enabling us to quickly fabricate custom aluminum, galvanized steel, and wooden frames without requiring costly new tooling runs.
We work with international logistics hubs in Shenzhen and Hong Kong to offer flexible transport options, including ocean freight, air express, and multimodal rail delivery. This ensures efficient transit to destinations across Europe, the Americas, and Southeast Asia. We also manage import and export documentation, certificates of origin, and custom customs declarations, saving time for your procurement team.
Our ongoing R&D roadmap targets lower resistance, green chemistry, and smart monitoring integrations.
We are developing nanofiber layers to improve dust loading capacity. By reducing the fiber diameter to sub-micron dimensions, we increase the surface area available to capture particles. This design maintains the same structural thickness, lowering overall system resistance and power use.
To support corporate environmental goals, our research team is developing biodegradable synthetic filter media and recyclable thermoplastic frames. These components reduce carbon footprint metrics during manufacturing and simplify filter disposal at end-of-life.
Future HVAC filtration systems will utilize built-in differential pressure sensors and RFID tracking. This setup monitors pressure drop changes in real-time, allowing operators to plan filter changes based on actual media dust load rather than fixed schedules.
